DETAILED DESCRIPTION

The present disclosure relates to facilitating the display of panels and sub-panels based on movement of an input device pointer such as, for example, a mouse pointer. In many instances, a user interface implemented in the form of a network page includes a panel with various elements. By placing or hovering an input device pointer over an element, users can invoke another panel (i.e., a sub-panel) that provides more selections/elements relating to that element. Such user interfaces are commonly offered by online retailers to facilitate electronic commerce.

Typically, when an element within a first, main panel is triggered via the hovering of an input device pointer over that element, information related to that element is shown in the form of a sub-panel, where the sub-panel may be shown to the right or left of the main panel containing the element. Depending on the path of the input device pointer, traversing from the main panel to the sub-panel on the right or left can cause unintentional triggering of other elements in the main panel located along the trajectory path of the input device pointer.

Various embodiments are disclosed whereby a network page is generated for display by a client, where the network page includes a first, main panel. As the user moves the input device pointer within the network page, the path of the input device pointer is monitored. A second, sub-panel is displayed in the network page according to the input device pointer hovering over an element in the first panel. Based on both the movement by the input device pointer and a delay period, the network page is updated. In the following discussion, a general description of the system and its components is provided, followed by a discussion of the operation of the same.

With reference to FIG. 1, shown is a networked environment 100 according to various embodiments. The networked environment 100 includes one or more computing devices 103 in data communication with one or more clients 106 by way of a network 109. The network 109 includes, for example, the Internet, intranets, extranets, wide area networks (WANs), local area networks (LANs), wired networks, wireless networks, or other suitable networks, etc., or any combination of two or more such networks.

The computing device 103 may comprise, for example, a server computer or any other system providing computing capability. Alternatively, a plurality of computing devices 103 may be employed that are arranged, for example, in one or more server banks or computer banks or other arrangements. For example, a plurality of computing devices 103 together may comprise a cloud computing resource, a grid computing resource, and/or any other distributed computing arrangement. Such computing devices 103 may be located in a single installation or may be distributed among many different geographical locations. For purposes of convenience, the computing device 103 is referred to herein in the singular. Even though the computing device 103 is referred to in the singular, it is understood that a plurality of computing devices 103 may be employed in the various arrangements as described above.

Various applications and/or other functionality may be executed in the computing device 103 according to various embodiments. Also, various data is stored in a data store 112 that is accessible to the computing device 103. The data store 112 may be representative of a plurality of data stores 112 as can be appreciated. The data stored in the data store 112, for example, is associated with the operation of the various applications and/or functional entities described below.

The components executed on the computing device 103, for example, include a user interface (UI) application 125, a network page server 119, and other applications, services, processes, systems, engines, or functionality not discussed in detail herein. The UI application 125 is executed to provide browser access to content that is served over the network 109. The network page server 119 acts as a gateway through which requests are received from clients 106 and responses transmitted back to the clients 106. It is understood that other applications and components, such as, an application implementing the hypertext transport protocol, may be executed on the computing device 103 beyond those described herein.

The computing device 103 may, in some embodiments, provide many different applications that are executed to provide services offered by an online merchant, a search engine, or other services that involve delivering content over a network 109. For example, the computing device 103 may execute applications that facilitate the ordering of goods online by customers by manipulating a user interface generated by the UI application 125 on a client 106. The computing device 103 may also execute a search engine, search indexer, or other services, etc., that facilitates the functionality of a search engine.

The client device 106 is representative of a plurality of client devices 106 that may be coupled to the network 109. The client device 106 may comprise, for example, a processor-based system, such as a computer system. Such a computer system may be embodied in the form of a desktop computer, a laptop computer, a personal digital assistant, a mobile device (e.g. cellular telephone, smart phone, etc.), set-top box, music players, web pads, tablet computer systems, or other devices with like capability. The client device 106 includes a display device 141 upon which various network pages 128 and other content may be rendered. The display device 141 may comprise, for example, one or more devices such as cathode ray tubes (CRTs), liquid crystal display (LCD) screens, gas plasma-based flat panel displays, LCD projectors, or other types of display devices, etc.

The client device 106 may be configured to execute various applications, such as a browser application 143 and/or other applications. The browser 143 may be executed in a client device 106, for example, to access and render network pages 128 embodied as web pages, or other network content served up by the computing device 103 and/or other servers.

In accordance with various embodiments, a user on a client 106 can purchase and/or view items via network pages 128 by manipulating a user interface implemented within a network page 128 rendered on the client 106. An item may refer to a product, good, service, software download, multimedia download, social networking profile, or any combination, bundle, or package thereof, that may be offered for sale, purchase, rental, lease, download, and/or any other form of consumption as may be appreciated.

To facilitate the generating of network pages 128 with certain user interface elements placed in panels within the network pages 128, the data store 112 in the computing device 103 may store network page data 131, where the network page data 131 includes one or more network page templates 133 for a given user interface. Each template 133 may include corresponding content 135 and data 137 stored in the data store 112. The network page templates 133 act as templates of network pages, such as dynamic network pages that may ultimately be populated with the content 135 and data 137. In addition, it is possible that network pages 128 may be generated using other approaches.

The content 135 may, for example, specify user interface elements that are arranged in a network page, such as, but not limited to, imagery, a page header, form elements (e.g., text entry fields, buttons, etc.), panels, menus, and other user interface elements as can be appreciated. As contemplated herein, the data store 112 may be representative of many different data stores included in a given system. The data store 112 may comprise, for example, a database or other data storage structure.

The UI application 125 facilitates the generating of network pages 128 provided to clients 106 in response to input provided by the client 106 comprising, for example, placement of an input device pointer such as a mouse pointer on one or more network pages 128. The UI application 125 embeds user behavior analyzer 130 code within the network page 128, where the user behavior analyzer 130 is configured to analyze movement of the mouse pointer to determine, for example, whether to modify/update the network page 128 being displayed on a display device 141 on the client 106. As a non-limiting example, the user behavior analyzer 130 may determine, based on movement by the mouse pointer, that the user intends to navigate to an element in a sub-menu currently being displayed and therefore, continue to display the sub-menu rather than displaying a different sub-menu.

For some embodiments, the UI application 125 generates network pages 128 for transmission to a client 106 that includes an embedded user behavior analyzer 130 for analyzing motion by an input device pointer to determine, for example, whether to invoke certain sub-menus within the network page 128. The user behavior analyzer 130 monitors movement of an input device pointer associated with an input device (e.g., a mouse, a touchscreen, stylus, etc.). In one embodiment, the UI application 125 embeds the user behavior analyzer 130 in the form of Javascript code or other type of code in the network page 128 to accomplish the functions described above.

For some embodiments, the user behavior analyzer 130 embedded in the network page 128 may be configured to sample an input device pointer position on a periodic basis and analyze the behavior and/or tendencies of a user on the client 106 based on the user's interactions with a network page 128 that is encoded by the UI application 125.

Based on the movement of the input device pointer, the user behavior analyzer 130 determines the trajectory angle and traversal rate of an input device pointer controlled by a user. Based on this, for example, the user behavior analyzer 130 can determine or predict if the user intends to navigate the input device pointer to a sub-menu associated with an element in the first, main panel. As described in more detail below, the user behavior analyzer 130 may be configured to execute a delay based on the trajectory of the input device pointer.

The techniques disclosed herein allow a user to navigate an input device pointer from a main panel to a sub-panel without unintentionally triggering a different sub-panel associated with another element in the main panel. For some embodiments, delay values 149 are predetermined and stored in the data store 112, where the data values 149 may be predetermined as a function of the angle of traversal. Prior to executing a delay, the user behavior analyzer 130 retrieves a delay value from the data store 112. For some embodiments, the delay values 149 may be stored, for example, in the form of a look-up table or matrix in the data store 112 or embedded in the network page 128.

Shown in FIG. 2A is a network page 128 generated by the UI application 125 (FIG. 1) and transmitted to a client 106 (FIG. 1). In the illustrated example, the network page 128 may include client side code, such as JavaScript® code, that monitors movement by an input device pointer 220. The network page 128 shown is an example of a user interface commonly offered by online retailers to facilitate electronic commerce.

As shown, the network page 128 includes a main panel 205 that includes a series of elements 208, 211, 214, where the elements may be associated, for example, with a category of items. As described above, an item may refer to a product, good, service, software download, multimedia download, social networking profile, or any combination, bundle, or package thereof, that may be offered for sale, purchase, rental, lease, download, and/or any other form of consumption as may be appreciated.

By hovering an input device pointer 220 over one of the elements 208 in the main panel 205, a second, sub-panel 217 providing additional categories/elements is displayed to allow the user to narrow down a selection. As shown, the second panel 217 may similarly contain multiple elements. In this non-limiting example, only two panels 205, 217 are shown. As can be appreciated, the network page 128 may include additional levels of panels.

In general, traversing from the first panel 205 to the second panel 217 located on the right can cause unintentional triggering of other elements in the main panel 205 located along the input device pointer 220 trajectory path. To illustrate, reference is made to the non-limiting example in FIG. 2A. While moving the input device pointer 220 from the element labeled “Sports” in the first panel 205 to the element labeled “Shoes,” the user may unintentionally trigger a sub-panel associated with another element in the first panel 205. In this illustration, for example, the user may unintentionally trigger a sub-panel associated with the element labeled “Clothing.”

Note that while the top of the second panel 217 in the example shown is aligned with the element 208 selected (i.e., “Sports”), the various embodiments described may be applied to other configurations/layouts of sub-panels. For example, shown in FIG. 2B is the same network page 128 with the second panel 217 placed in a position such that the selected element in the first panel 205 is centralized with respect to the second panel 217. As can be appreciated, due to the layout shown in FIG. 2B, the user may unintentionally trigger a sub-panel associated with another element in the first panel 205, where the element is to the top or bottom of the selected element (i.e., the element labeled “Sports”).

As described in detail below, for some embodiments, the user behavior analyzer 130 (FIG. 1) executes a delay prior to updating/modifying the network page 128, where updating/modifying the network page 128 may comprise, for example, invoking a different sub-panel 217 than the one shown. For some embodiments, the delay is a predetermined delay set according to a trajectory path with respect to a point of reference comprising a starting point of the input device pointer 220 on the first panel 205.

Shown in FIG. 3 is a starting point 302 of the input device pointer 220 used for determining the trajectory path of the input device pointer 220. For some embodiments, the trajectory is generally categorized according to a discrete number of directions comprising a north direction, south direction, east direction, west direction, northeast direction, southeast direction, northwest direction, and southwest direction (or in the alternative, an upward direction, a downward direction, a right direction, a left direction, an upper right direction, a lower right direction, an upper left direction, and a lower left direction). As described below, the delay executed by the user behavior analyzer 130 may be a function of the trajectory path.

In accordance with some embodiments, the direction that the input device pointer 220 is moving may be determined using a sliding window technique that calculates various distances. Specifically, mouse movement is sampled at an interval and points are stored in a sliding first-in first-out (FIFO) window of size n. At each interval, the first (i.e., “oldest”) and last (“newest”) points in the window are compared with the current point to determine mouse direction. The “newest” point is defined as the point sampled immediately before the current point of the input device pointer 220. The oldest point is dequeued from the window and the current point is enqueued to the window. Note that the oldest, newest, and current points may be the same value for various reasons including, for example, movement by the input device pointer 220 and the number of items currently stored in the window at the time of calculation.

The following is just one possible implementation for incorporating the sliding window technique. First, a window size is defined, and the x and y coordinates of the input device pointer 220 are monitored. A “newest” distance is then calculated based on the following:

${{newest}\mspace{14mu} {distance}} = {\sqrt{\left( {{current\_ x} - {newest\_ x}} \right)^{2} + \left( {{current\_ y} - {newest\_ y}} \right)^{2}}.}$

An “oldest” distance is calculated based on the following:

${{oldest}\mspace{14mu} {distance}} = {\sqrt{\left( {{current\_ x} - {oldest\_ x}} \right)^{2} + \left( {{current\_ y} - {oldest\_ y}} \right)^{2}}.}$

For some embodiments, if the newest distance is greater than a predetermined threshold, the newest distance is used and a reference point is set to the “newest” point. If the newest distance is not greater than the predetermined threshold, the oldest distance is used, and the reference point is set to the oldest point in the sliding window. Based on this, the direction may be derived as follows:

direction=round(arctan(current_(—) y−referencepoint_(—) y, current_(—) x−referencepoint_(—) x)*4/π)*45.

If the magnitude of the distance is greater than a second predetermined threshold, then a determination is made on whether the direction is positive or negative. If the direction is a negative value, then a positive value of the direction is derived by multiplying the direction by a value of −1. If the direction is a positive value, the direction is calculated as (new) direction=360−direction. If the magnitude of the distance is not greater than the second predetermined threshold, then the direction is considered to be indeterminate. For some embodiments, a default delay is assigned for such cases.

FIG. 4A illustrates how delay values are assigned as a function of the direction. For some embodiments, the trajectory of the input device pointer 220 (FIG. 2A) is categorized according to one of eight directions. While extending the hover triggering delay according to a global, constant delay may address trajectory issues in certain directions (e.g., the northeast, east, and southeast direction), this can substantially slow down navigation of the input device pointer 220 in other directions (e.g., north and south). Therefore, various embodiments incorporate a variable delay value based on the location of a second panel 405 with respect to a first panel 402. Note that while eight directions are shown in the non-limiting example of FIG. 4A, the degree of granularity is not limited to eight directions. For example, delay values for up to three hundred and sixty degrees can be implemented as well.

Shown in FIG. 4A are two panels 402, 405 where the second panel 405 is located to the right of the first panel 402. In this non-limiting example, the delay values associated with trajectory paths towards the second panel 405 are assigned higher values to reduce the possibility of unintentionally triggering other panels. In this non-limiting example, delay values 3-5 are assigned a greater value than the remaining delay values (delay values 1, 2, and 6-8). The delay values are assigned according to placement of the panels 402, 405 with respect to one another. As another example, for user interfaces where the second panel 405 is placed on top of the first panel 402, the delay values corresponding to that direction (e.g., delay values 1-3) would be assigned a higher value relative to the remaining delays values.

As shown in FIG. 4B, for some embodiments, the trajectory path of the input device pointer 220 (FIG. 2A) is categorized according to the closest direction (the north direction, south direction, east direction, west direction, northeast direction, southeast direction, northwest direction, and southwest direction). In the example shown, based on the angle of traversal by the input device pointer 220, the user behavior analyzer 130 (FIG. 1) retrieves delay value 3 from among the delay values 149 (FIG. 1) stored in the data store 112 (FIG. 1) of the computing device 103 (FIG. 1) and executes a delay equal to this value.

For some embodiments, the user behavior analyzer 130 also determines whether the input device pointer 220 traverses a minimum distance from the starting point 302 (FIG. 3) of the input device pointer 220. For example, in some cases, the user may move the input device pointer 220 in the direction of the second panel 217 (FIG. 2A) but such that the input device pointer 220 stays within the first panel 205 (FIG. 2B) when the delay period expires. In such cases, even though the input device pointer 220 is moving in the direction of the second panel 217, the user behavior analyzer 130 determines that the user intends to select another element in the first panel 205 (FIG. 2A) and invoke another panel other than the panel 217 already being displayed.

For example, the user behavior analyzer 130 may modify the user interface to display a panel associated with the element immediately above the current element. For other embodiments, the user behavior analyzer 130 may also examine the traversal rate of the input device pointer 220. If the traversal rate meets or exceeds a minimum threshold rate, the user behavior analyzer 130 may determine that the user intends to navigate to the second panel 217 currently being shown. In contrast, the user behavior analyzer 130 may determine that slow movement of the input device pointer 220 indicates that the user intends to navigate to a different element in the first panel 205.

In some cases where the trajectory angle of the input device pointer 220 is not discernible (due, for example, to a tight, spiraling motion by the input device pointer 220), a default delay value may be retrieved and executed by the user behavior analyzer 130. By executing a delay, the user behavior analyzer 130 allows the user to traverse the input device pointer 220 to its intended destination without unintentionally triggering another panel.

Shown in FIG. 5A is an alternative embodiment for reducing unintentional triggering of panels. For some embodiments, a triangle technique is implemented whereby a triangular region 501 is defined based on an initial starting point 302 of the input device pointer 220 and corners 505, 507 of the second panel 217. Generally, the triangle technique comprises two aspects: 1) scenarios where the input mouse pointer 220 moves a minimum distance (i.e., characterized as “ordinary movement”); and 2) scenarios where the input mouse pointer 220 only moves an incremental distance where the trajectory angle is not discernible (i.e., “small movement”). The first aspect relates to typical input device pointer 220 movements that involve traversing across more than one pixel at a time, whereas the second aspect generally relates to very small movements by input device pointer 220 typically on the order of less than one pixel.

For scenarios in which the input mouse pointer 220 moves more than one pixel (i.e., “ordinary movement”), a triangular region 501 is defined based on the initial position 302 of the input device pointer 220. The other two vertices comprise corners 505, 507 of the second panel 217 closest to the first panel 205. FIG. 5B illustrates movement of the input device pointer 220 inside and outside the triangular region 501. If the input device pointer 220 remains in the triangular region 501, the user behavior analyzer 130 (FIG. 1) determines that the user intends to navigate the input device pointer 220 to an element in the second panel 217 (FIG. 5A). Based on this, the user behavior analyzer 130 executes a delay, thereby providing the user more time to move the input device pointer 220 to its final destination.

For embodiments utilizing the triangle technique, a constant delay value may be utilized. If the input device pointer 220 moves again before the delay period expires, the user behavior analyzer 130 repeats the calculation and determines again whether the input device pointer 220 is moving towards the second panel 217 currently being displayed. For this second calculation, a new triangular region is defined based on the current position of the input device pointer 220 and the corners 505, 507 (FIG. 5A) of the second panel 217 currently being displayed. The process is repeated until the input device pointer 220 eventually falls outside the newly calculated triangle or the input device 220 pointer stops moving.

If the input device pointer 220 stops moving or falls outside the triangular region 501 but is still in the first menu 205 area, the UI application 125 updates/modifies the user interface to display a different, second panel than the second panel 217 previously shown. In this scenario, the user behavior analyzer 130 determines that the user intends to select a new element within the first panel 205. If the input device pointer 220 falls outside the triangular region 501 but is now inside the second panel 217, the UI application 125 does not update/modify the user interface. Instead, the original, second panel 217 remains on the user interface.

Note that while the example shown in FIGS. 5A and 5B depict the second panel 217 being placed to the right of the first panel 205, the triangle technique described above may also be implemented for any panel layout (e.g., left/right, right/left, top/bottom, bottom/top).

If the input device pointer 220 movement is very small (e.g., on the order of only one pixel), the user behavior analyzer 130 may need to examine the prior positions of the input device pointer 220. This additional step is performed because coordinates for input device pointers 220 and other display elements are divided into discrete square units (i.e., pixels), and a meaningful triangle calculation is not possible at such small scales.

To illustrate, reference is made to FIG. 6, which illustrates an exploded view of a user interface at the pixel level. Suppose that the shaded pixels shown are associated with one element 602 and that the pixels below are associated with a different element 605. Assume for this illustration that pixel 611 contains the current position 627 of the input device pointer 220 (FIG. 2A) and that pixel 608 contains the prior position 624 of the input device pointer 220. FIG. 6 shows how the trajectory angle may differ based on the position of the input device pointer 220 in the two pixels 608, 611. In one scenario, positions 614, 617 of the input device pointer 220 define one trajectory angle, while positions 624, 627 define a different trajectory angle even though both sets of positions occupy the same two pixels 608, 611.

To address such scenarios, the user behavior analyzer 130 (FIG. 1) examines other prior positions of the input device pointer 220. In accordance with such embodiments, the user behavior analyzer 130 looks at the current position 617 (position[n]) of the input device pointer 220 in addition to the two prior positions (position[n−1] and position[n−2]). As shown in FIG. 6, the position 620 (position[n−2]) of the input device pointer 220 prior to position 614 (position[n−1]) is located in pixel 618. The user behavior analyzer 130 examines the coordinates of the prior position 614 to determine if the x-coordinate is unchanged and if the y-coordinate has only moved by one pixel relative to the current position 617 (position[n]). If this applies, the user behavior analyzer 130 examines the position 620 prior to the last position 614 (i.e., the “two-prior” position) and determines if the x-coordinate of the (two-prior) position 620 is less than the x-coordinate of the current position 617. If this applies, a short delay is executed and the user behavior analyzer 130 attempts to perform the triangle technique associated with ordinary movement. If the x-coordinate of two-prior position is the same as or greater than the x-coordinate of the current position 617, then the triangle technique associated with ordinary movement is performed without any delay. Note again that the small movement technique may be implemented for any panel layout (e.g., left/right, right/left, top/bottom, bottom/top).

Referring next to FIG. 7, shown is a flowchart that provides one example of the operation of the user behavior analyzer 130 (FIG. 1) according to various embodiments. It is understood that the flowchart of FIG. 7 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the user behavior analyzer 130 as described herein. As an alternative, the flowchart of FIG. 7 may be viewed as depicting an example of steps of a method implemented in the computing device 103 (FIG. 1) according to one or more embodiments. The user behavior analyzer 130 is executed in the client 106 (FIG. 1).

Beginning with box 703, the user behavior analyzer 130 identifies the starting point 302 (FIG. 3) of the input pointing device 220 (FIG. 2A) within a network page 128 (FIG. 2A) displayed on the client 106. In box 706, the user behavior analyzer 130 determines the trajectory path of the input pointer device 220. In box 709, the user behavior analyzer 130 retrieves a delay value based on the determined trajectory path. In box 712, the user behavior analyzer 130 waits a period of time equal to the retrieved delay value. In box 715, the user behavior analyzer 130 modifies the network page 128 based on the current position of the input device pointer 220. Thereafter the user behavior analyzer 130 ends as shown.

Referring next to FIG. 8 shown is a flowchart that provides one example of the operation of the user behavior analyzer 130 (FIG. 1) according to alternative embodiments. It is understood that the flowchart of FIG. 8 provides merely an example of the many different types of functional arrangements that may be employed to implement the operation of the user behavior analyzer 130 as described herein. As an alternative, the flowchart of FIG. 8 may be viewed as depicting an example of steps of a method implemented in the computing device 103 (FIG. 1) according to one or more embodiments. The user behavior analyzer 130 is executed in the client 106 (FIG. 1).

Beginning with box 803, the user behavior analyzer 130 detects motion by the input device pointer 220 (FIG. 2A). In box 804, the user behavior analyzer 130 determines whether the motion by the input device pointer 220 may be categorized as “ordinary movement” or “small movement,” described above. For ordinary movement, the user behavior analyzer 130 identifies a triangular region 501 (FIG. 5A) (box 806).

In box 812, the user behavior analyzer 130 waits a period of time equal to a predetermined delay value. In box 813, a determination is made on whether the input device pointer 220 is still within the triangular region. If the input device pointer 220 is no longer within the triangular region, then the user behavior analyzer 130 proceeds to box 818, where the network page is updated based on the final position of the input device pointer 220. If the input device pointer 220 is still within the triangular region, then the user behavior analyzer 130 proceeds to box 815. In box 815, if the input device pointer 220 moves again prior to expiration of the delay, then the user behavior analyzer 130 proceeds back to box 804. If the input device pointer 220 does not move prior to expiration of the delay, then in box 818, the user behavior analyzer 130 updates the network page based on the final position of the input device pointer 220.

Referring back to box 804, if the motion by the input device pointer 220 is categorized as small movement (box 805), the user behavior analyzer 130 examines the two prior positions with respect to the current position of the input device pointer 220, as described above. If necessary, the user behavior analyzer 130 waits a period of time equal to a predetermined delay and then proceeds back to box 804 to determine whether the motion by the input device pointer 220 may be categorized as ordinary movement.
